The invention relates to a sampling device for taking a water sample under pressure from a large depth in a hole bored in the earth. The sampling device comprises parting elements (1) for separating a sampling interval (2) from the rest of the bore hole (3); a flow pipe (4) for extracting the water from the sampling interval; a sample container (5); a sampling pipe (6) for passing up the water supplied by the flow pipe to a point above the sampling device; a valve (7) for directing the water flow directly from the flow pipe into the sampling pipe or from the flow pipe via the sample container into the sampling pipe and for closing and opening the sample container; and a pressure pipe (8) for supplying and operating pressure to the parting element (1) and the valve (7).
